Actually i tried to export documnet layout (File->Export->Export Docuement layout) and stores in our location where we want. Now this folder contains different number of xml files but when i'm trying to import it is not showing any file for selection.

You have to export this layout in the any folder and try to create another new file by using this layout file by import this layout file in the new file it will create a chart and sheets that you have in file from where you export it but not the data.

After Export you have to Import this from File -> Import -> Import Document layout

Export Document Layout ( Contains whole documnet suppose there is 5 sheet in qvw file it will export it same)

Export Sheet Layout ( Only perticular sheet that you open and export its layout )

2. After this you need to Import this file ( "YourQVWFile.Layout.xml" ) into any new QVW new file by ceating new qvw file and after dowing this all Charts, Sheets , Objects, Expressions, Table scripts but without data of the qvw file is created you need to reload it.

This feature has changed from version 10 on. Copied from version 10 Release Notes:

Import layout is not possible from Version 10 to Version 10. The functionality is kept for backward compatibility with Version 9, but for Version 10, we recommend that you create a project directory adjacent to your QlikView file and then move / copy the files from that project directory if you want to copy layout from one document to another.

You can export the layout, but not give a name. All objects will get names by default in the folder specified: SH01.xml for the first sheet layout, CH01.xml for the first chart layout, and so on, plus some other general properties xml files.
